| Abstract: | We use a simple, collision-based, discrete, random abrasion model to compute the profiles for the stoss faces in a bedrock
abrasion process. The model is the discrete equivalent of the generalized version of a classical, collision based model of
abrasion. Three control parameters (which describe the average size of the colliding objects, the expected direction of the
impacts and the average volume removed from the body due to one collision) are sufficient for realistic predictions. |
